Improvement In Technology For The Visually Impaired.
For decades, technology has progressed dramatically for the visually impaired. New ways are being thought up in order have different opportunities for those who do not have the ability to see. An example is a surgical option. Electrode arrays are placed in the retina of the eye and electrically stimulate the living retinal cells to activate a basic visual sense. Argus II is an example of an implant and is the only approved retinal implant in the US and Europe. Though it has problems considering the resolution is very low. Another option is sensory substitution. Modern Tactile devices use a camera, device and display to convert visual stimuli into little electrical signals onto a person’s tongue. Converting sight into sound is another way. The signal is reverted back to the user by using headphones, a pc or smartphone, and a camera to obtain the information.
